Я пытаюсь научиться управлению базой данных. Это код, который я создал на основе примера из учебника: 

    drop database `Pine_Valley_Furniture_Company`;

CREATE DATABASE `Pine_Valley_Furniture_Company` DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

USE `Pine_Valley_Furniture_Company`;

CREATE TABLE IF NOT EXISTS `CUSTOMER` (
  `ID` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT = 100,       -- I made the decision to start the auto-increment from 100 to reserve ids below 100 for special customers (company subsidiaries, government clients) or special placeholder (error) values 
  `Name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,      -- Can't have a nameless customer, so 'NOT NULL'
  `Address` varchar(30) COLLATE utf8_unicode_ci,            -- Address fields are not required, since a customer might do a pick up at the store, so I didn't use 'NOT NULL' for these fields
  `City` varchar(20) COLLATE utf8_unicode_ci,
  `State_` char(2) COLLATE utf8_unicode_ci,                 -- 'state' is a reserved keyword, so I used 'state_' for the column name instead
  `Postalcode` varchar(10) COLLATE utf8_unicode_ci

INSERT INTO `ORDER_LINE` (`OrderID`, `ProductID`, `Orderedquantity`) VALUES(104, 18013, 2);




CREATE TABLE IF NOT EXISTS `ORDER_` (                           -- Named it 'ORDER_' instead of 'ORDER', since ORDER is a reserved keyword

Когда я пытаюсь запустить любой из этих сценариев через командную строку mysql.exe --user = root --password -s <"E: \ Проектирование и управление базой данных \ Lab 2 \ shirts4mike-1.sql" это дает мне кучу ошибок ОБА для моего сценария и примера из учебника. </p> 

 ERROR 1064 (42000) at line 7: You have an error in your SQL syntax;
 check the manual that corresponds to your MariaDB server version for
 the right syntax to use near '= 100,   `Name` varchar(25) COLLATE
 utf8_unicode_ci NOT NULL,   `Address` v' at line 2

Если я удалю автоинкремент отовсюду, он все равно лает

Пожалуйста, помогите! Что я делаю не так (при условии, что код учебника также дает ошибки)? Я сам по себе, инструктора нет. Это очень запутанно.

`ID` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT = 100,

Это не синтаксис, который распознает MySQL.В вашем учебнике говорилось, что вы можете объявить начальное значение ИИ там?

Если вы хотите запустить автоинкремент с 100, сделайте следующее: 

CREATE TABLE IF NOT EXISTS `CUSTOMER` (
    `ID` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT, 
    ... other columns ...
) ENGINE=InnoDB AUTO_INCREMENT=100 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Вы также можете изменить значение ИИдля таблицы в любое время после ее создания: 

ALTER TABLE `CUSTOMER` AUTO_INCREMENT=200;

Если в таблице есть строки данных, изменение значения AI таким образом не упадет ниже наибольшего значения идентификатора, существующего в таблице.
